PEOPLE across Huddersfield are already recycling a good proportion of their household waste.
Now Kirklees Council is bidding to go even greener.
About 90% of homes in the council's area are part of the green bin scheme.
People regularly fill them up with cardboard, paper, plastic bottles and tins.
The council is now looking to extend its glass collection service through use of green boxes.
There are 22,000 properties at the moment with this collection facility - and this is set to double this summer.
Dave McMahon, the council's environmental projects manager, said Kirklees was hitting all its recycling targets.
He said it surpassed its statutory target of recycling or composting 14% of household waste in 2003/2004.
He said the actual performance was 14.2%.
This equates to an impressive 14,000 tonnes of green bin material being taken to the SITA recycling facility on Vine Street, Hillhouse.
And Mr McMahon said the council was well on course to hit its 21% target for 2005/06.
"For 2005/2006 we will actually be recycling about 40% of our household waste if we could include things like steel cans, ash, rubble etc."
He said only certain materials could be counted under Government guidelines.
Some things, such as steel cans and ash (after incineration), are being recycled but cannot be counted.
"To quote 21% we feel doesn't give the full picture as to how well we're managing waste."
Asked about the importance of recycling Mr McMahon said: "Usually, recycling of any material will use less energy. Obviously it will use fewer natural resources.
"Also, it uses less energy to produce a new product.
"Say, for instance, you have got an aluminium can. It's a lot more energy-efficient to melt that can down and produce a new one."
He said energy was saved because mining the ore wasn't required and then you saved on all the subsequent processing.
"The recycling of materials, or the use of recycled materials to produce new materials, will require less energy, and energy use is a major contributor to global warming."
Kirklees's recycling scheme started in the mid-90s and Mr McMahon said there had been good feedback over the years.
He added: "It's being used well. The quality of the material is very good. Our contractor always tells us that the quality is the best they see."
He said the level of contamination of recyclable materials, such as dirty packaging, was also very low in the Huddersfield area.
